Standard System Features
Feature Description Benefits
Tracking Generator (option)
View the performance characteristics of many
RF devices with this convenient tracking
generator. A sweep range from 5 KHz to 1 GHz,
with a resolution of 1 Hz, permits accurate
device alignment.
Allows the operator to quickly and easily
diagnose critical problems with receiver front
ends, IFs, helical filters, cavities, combiners
and duplexers.
Full Featured Spectrum Analyzer
The R2590 comes complete with a powerful,
yet very easy to use spectrum analyzer.
Independent Start, Stop, and Span settings
permit ready adjustment of the displayed
spectrum from a 5 KHz window to a full 1 GHz
span width. A fully adjustable reference level,
and a set of four individual markers allows
for precise measurements of levels and
frequencies.
Stop, Average, Peak Hold functions and
one-button measurements such as Occupied
Bandwidth make for a powerful analyzer that
can handle almost any situation.
Our unique ‘Scanning Spectrum Audio’
function replaces the typical ‘look and listen’
capability by tuning the receiver (and the
recovered audio) to an adjustable marker
frequency, rather than the center frequency of
the spectrum display.
The R2590 comes packed with features
typically found on stand-alone spectrum
analyzers, and much more.
This feature is handy when attempting to
identify a variety of signals without the need
to continually change the center frequency of
the spectrum display.
AM/FM Receiver
With a typical sensitivity of less than 2
microvolts at the antenna port, the R2590 can
be used for the off-the-air monitoring of remote
transmitters. Variable squelch aids in picking
up weak signals, but can be set tighter to
ensure the proper S/N ratio for measurement
accuracy.
This feature reduces service costs by enabling
frequent preventative maintenance checks for
system degradation or interference identification without ever leaving the shop.
AM/FM/PM Generator
The R2590 includes a 250 KHz to 1 GHz
AM/FM/PM signal generator that has an
adjustable output level from –125 dBm to
–10 dBm.
The generator output port is fuse-protected,
assuring against damage by the inadvertent
application of power, therefore saving a trip to
the repair shop.
Selectable metering includes a ‘One Button’
SINAD measurement with adjustable target
setting. The R2590 will automatically determine
the RF level needed to produce a specified
SINAD reading.
This flexible signal generator reduces receiver
test time by displaying all the necessary
control information simultaneously. The wide
range of output levels cover all manner of
troubleshooting situations.
The R2590 simplifies routine measurements
with ‘One Button’ convenience.
Full Band Duplex
Offset Generator
Full output level control from –125 dBm to
–10 dBm over the entire frequency range of
the instrument is available from the duplex
offset generator.
Duplex frequency offsets are also fully
variable, from 0 Hz to 1 GHz in 1 Hz steps.
The duplex generator provides enhanced
capability to service equipment such as
repeaters and full duplex radios.
The 1 Hz frequency offset resolution extends
functionality to cross-band repeaters and
component level receiver and transmitter
troubleshooting.

Feature Description Benefits
Standard System Features – continued
Broadband and Selective
Power Meters
The built-in power meter automatically
switches from a selective meter at low power
levels, to a true RMS broadband meter at
higher power levels. Accurate power meter
measurements can be made up to 150 Watts.
Accurately make true RMS power meter
measurements without a stand-alone power
meter, or bulky external attenuators. The R2590
can safely dissipate up to 200 watts of
RF power, 150 watts continuously (@20˚C).
Electronic Software Updates
A high speed serial port and flashable memory
permit programming firmware updates from an
external PC. The standard bi-directional RS232
port is also available for remote control of the
R2590 by an external controller.
Quick and easy access to future software
updates.
Cable Fault/Antenna Analyzer
(Option)
The return loss bridge included with the
Antenna Analyzer option is specially designed
to interface to the R2590. It plugs directly into
the ‘antenna in’ and ‘generate out’ ports – no
external cables needed.
In conjunction with the tracking generator
feature, it allows you to view the frequency
characteristics of an attached antenna, while
providing a one-button measurement for both
SWR and return loss.
The Cable Fault feature assists the technician
with isolating cable defects and anomalies. A
high precision, FFT based Frequency Domain
Reflectometer (FDR) allows fault analysis out
to 800 feet, with a resolution down to 4 inches.
Quickly and easily verify the tuned frequencies
of an antenna.
Visually determine the operating
characteristics of an antenna.
This feature allows validation of cable
performance by detecting high insertion loss
and faulty connectors and couplers, while also
verifying cable lengths. In addition, quick
setup, and fully automatic operation, maximize
your on-site productivity.
High Stability Oscillator (Option)
The standard oscillator in the R2590 is an
OCXO rated at a temperature stability of
.2 ppm. With a warm-up time of less than
3 minutes, you can quickly be assured of
accurate test results.
The optional high stability oscillator is also an
OCXO, yet increases the temperature stability
to .02 ppm. Accuracy is guaranteed within
5 minutes of turn-on.
Be assured of accurate frequency
measurements within minutes of turn-on.
Current consumption of the high stability
oscillator is comparable to the standard
oscillator, causing minimal effect on
battery life.
Audio Modulation Synthesizer
The standard audio modulation synthesizer
includes dual tone, DTMF, and PL/DPL
(CTCSS/DCS) generators. The dual tone
generators are fully adjustable up to 25 KHz
in .1 Hz steps.
The optional paging encoder adds support for
5/6 tone, 2-tone, a user defined programmable
sequence, plus digital paging formats.
This feature ensures overall system
performance by providing readily available
built-in modulation sources.
Internal Battery/External
DC Operation
The R2590 can be powered from a variety of
AC and DC sources. When on the bench, the
AC mains will automatically accept from 100
VAC to 240VAC (50 to 60 Hz). At remote locations, the R2590 can be powered from external
DC sources. For the ultimate in versatility, the
internal battery option will power the unit for
up to 2 hours. The built-in charger keeps the
battery fully charged when plugged in to an
AC source.
The R2590 was designed to go where you go.
Typical power consumption when used with
a DC power source is only 35 watts, assuring
extended operation when used in remote
field locations.

Standard System Features – continued
CLEARCHANNEL LTR (Option)
The CLEARCHANNEL LTR trunking option adds
the capability to simulate an LTR repeater
system. Complete versatility is provided by
selectable messaging parameters including;
Area, Goto/In Use, Home, Group, and Free.
An “Auto Setup” function simplifies data entry
by automatically capturing the repeater and
mobil data settings.
Selectable messaging types, such as
Continuous, Idle, Busy, Oneshot, and
Handshake, permit comprehensive
troubleshooting of LTR repeater systems.
One button configuration of the R2590
minimizes setup errors, and allows more time
for troubleshooting the LTR radio system.
